How did Rene descartes come up with coordinate geometry? - Answers

René Descartes developed coordinate geometry by combining algebra and Euclidean geometry. He introduced a system of using pairs of numbers to represent points in a plane, which allowed geometric shapes to be expressed as algebraic equations. This innovative approach enabled the translation of geometric problems into algebraic form, facilitating their analysis and solution. His work laid the foundational framework for modern mathematics and the Cartesian coordinate system.
